一、前言为了支援农业,鞍钢试制了轴承套用“GCr15热轧无缝钢管”。该产品系拖拉机上“密封油套”的另件,用 GCr15轴承管制造,钢管尺寸为φ108×12.5和φ89×12.5毫米两个品种。由于在试轧中採取了轧终快速冷却措施,保证了网状碳化物没超出规定;和採用了合理的成品退火制度,使退火后的组织满足了技术条件的要求。一级品率φ108×12.5和φ89×12.5毫米的管子分别达到94.39%和100%。GCr15滚珠轴承套用钢管试制的成功,为
I. Introduction In order to support agriculture, Anshan Iron and Steel trial production bearing “GCr15 hot-rolled seamless steel pipe ”. The product is a tractor “seal oil jacket ” of another piece, with GCr15 bearing pipe manufacturing, pipe size φ108 × 12.5 and φ89 × 12.5 mm two varieties. As a result of the rapid rolling in the rolling test taken measures to ensure that the network did not exceed the provisions of carbide; and the use of a reasonable system of finished annealing, the annealed tissue to meet the technical requirements. The pipes of the first grade of φ108 × 12.5 and φ89 × 12.5 mm reach 94.39% and 100% respectively. GCr15 ball bearing sleeve steel pipe trial success
